CIGAR-MAKING MACHINE.

To all whom it may concern:

Be it known that I, JULIUS HAARER, a subject of the German Emperor, andresident of Frankfort-ontl1e-Main, Germany, have invented a certain newand useful Improvement in Cigar-Making Machines, of which the followingis a specification.

The present invention relates to improvements in machines for producingcigar bunches. Such machines are usually provided with a feed channel inwhich the tobacco is moved along by means of conveyer bars and is at thesame time pressed down on to the bottom by means of bars. These pressurebars have previously been fixed stationary in the machine; as however,the channel has to be exchanged according to the different forms ofcigars it may easily occur that with a broad channel the pressure barswill not sufficiently cover the same to prevent the tobacco from rising.

The advantages presented by this invention consist therein that thepressure bars are substituted by a grating pressing resiliently upon thetobacco, the spacing of the rods of said grating being adjusted to suitthe width of the channel employed.

According to the invention the conveyer bars which are disposed betweenthe rods of the grating are arranged so that the distances between themcan be varied correspondingly with the spacing of the grating rods.

The invention is illustrated in the accompanying drawings in whichFigure 1 is a plan, Figs. 2 and 3 are cross sections on the line A B ofFig. 1 representing two different working positions. Fig. 4: is a frontelevation to a smaller scale showing the channel in section and also theoperating means. Fig. 5 shows in plan a modification of the grating indifierent breadths for depressing the tobacco.

The channel Z9 is interchangeably arranged within the machine frame a.Above said channel are arranged conveyer bars 01 which are toothed ontheir lower edges and which are movable transversely up on the shafts fand The transverse movement is effected by a right and left handed screwspindle 2 engaging the two outside conveyer bars by means of its threadand the middle one by means of a collar 8. The outside conveyor bars areconnected with the intermediate bars by means of so called shears 4 asshown in Figs. 2 and 3. Upon rotation of the spindle 2 the dis-Specification of Letters Patent.

tance between the conveyer bars can therefore be altered as desired. Theactuation is eifected in known manner by means of a shaft 79 carrying acam disk 9 and a tappet 0. The cam disk g actuates a bell crank lever1", t, which is connected by a link 4) to levers w mounted on a shaft .2and pivotally connected at their free ends with the shaft 7. The tappet0 engages a lever is pivoted at y and carrying a shaft 00 having twolinks 71 pivotally connected with the shaft When the shaft is rotatedthe conveyor bars (Z are moved through the intermediary of the members 7t, 'v, to, f in conjunction with the members 70, a2, 2', f in suchmanner that they will describe an elliptical path, dipping into the moldwhen moving toward the left, and being raised slightly above the moldwhen moving toward the right (see Fig. 4 so that the tobacco containedin the mold will be carried with them only in one direction. Themovement of the bars is indicated at the top of Fig. 4; by the smallellipse of arrows. The mold b is covered over its whole width by agrating consisting of rods 0 disposed between the conveyer bars. Therods 0 are pressed down resiliently against the tobacco contained in themold by means of springs 1, thus preventing the tobacco from rising.

In order to produce cigar bunches of different form, channels ofdifferent breadth are placed into the machine frame a. If for instance anarrower channel 5 (Fig. 2) is exchanged for a wider one I) (Fig. 3) thedistance between the conveyer bars (l is correspondingly altered tosuit, by rotating the spindle 2, as will be seen by comparing Fig. 2with Fig. 3. By altering the posit-ion of the conveyer bars (Z thegrating rods 0 disposed between them are correspondingly moved (Figs. 2and 3) so that the spacing is also always adjusted to suit the width ofthe channel. Instead of forming the grating of independent rods,gratings as shown in Fig. 5 may be used, in which the rods are rigidlyconnected at their ends, and are at different distances apartcorresponding to the different widths of the molds. These gratings areinserted in the corresponding channel and also pressed down upon thetobacco by means of springs. Instead of subjecting the grating to theaction of springs, gratings resilient in themselves may be used forpressing down the tobacco. Variation of the spacing of the conveyer barsmay also be eliected in other ways and not by shears as illustrated.

Having now described my invention I declare that what I claim and desireto receive by Letters Patent of the United States is 1. In acigar-making machine, devices for pressing down and conveying thetobacco, comprising in combination interchangeable channels, gratingscomposed of rods for pressing down and conveying the tobacco, conveyerbars entering into the spaces between rods of said grating, and meansfor varying the spacing of said conveyer bars.

2. In a cigar-making machine, devices for pressing down and conveyingthe tobacco, comprising in combination interchangeable channels,gratings composed of rods for pressing down and conveying the tobacco,conveyer bars entering into the spaces between rods of said grating,means for varying the spacing of said conveyer bars and actingtherethrough to vary the spacing of said rods.

A cigar making machine comprising in combination, a frame,interchangeable channel members therefor, elements for pressing andconveying the tobacco in said channel member, and means for adjustingsaid elements to correspond to the Width of the channel used.

4. A cigar making machine comprising in combination, a frame, a channelmember therefor, elements for compressing and conveying the tobacco insaid channel member, mechanism connecting said elements to permitmovement thereof and maintain the same uniformly spaced, and means foradjusting said elements toward and from each other.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
